there has been much talk in other forums around here about wildlife and custom animation for them. The most common being Dogs (in and around cities and farms), Cows and other farm animals (near farms...duh), Snakes and insects (near swampy or wetland type areas or near water), and other various common things like squirrels in forests... I think BIS had great ideas to put those sound files of animals in the sound file that came with the game...but i think we need to follow up on it and make the animals themselves.
Plus wouldnt it be fun to go cowtipping...with RPG's?
